Paging to poll uplink data transmission in WirelessMAN
OFDMA system

Background
As we agreed at the last session, the paging message can be used to poll M2M devices for uplink transmission. However,
for 16p we also agreed a group paging to reduce paging overhead for large number of devices. So some parameters shall
be included either for an individual paging or a group paging. Also, MOB_POLL-ADV message is optimized by
removing unnecessary parameters.
Additionally, this contribution proposes a new parameter, ‘reception of polling indicator’ in RNG-REQ message. This is
for an M2M device to indicate missing of polling within the Max number of paging cycle. By doing so, the BS can realize
a ranging request from the device is reasonable to be accepted even if the transmission type of the device is set to 1
(means the device shall receive polling in order to send uplink data during idle mode).
Text Proposal
[Remedy1:] Modify texts as following in page 2 line 45:
[Note - Remedy1: Since M2M_POLL_ADV is used to poll some M2M devices (by including MAC Address hash) which
are allowed to send uplink data at the paging cycle, it is enough to include those MAC address hash without additional
action code. In that case, if an M2M device finds its MAC address hash in MOB_POLL-ADV message, it considers that it
can send uplink data during this paging cycle.
6.3.2.3.60 M2M_POLL-ADV (M2M broadcast paging) message
An MOB_POLL-ADV message may be transmitted by a BS to indicate periodic uplink data transmission from M2M devices in idle
mode. The M2M_POLL-ADV message shall be sent on the Broadcast CID or Idle Mode Multicast CID during the BS paging interval.
The M2M_POLL-ADV is to be broadcast on the same downlink frame as MOB_PAG-ADV., so the devices can receive the message
after waking up from the idle mode. If an M2M_POLL-ADV message includes M2M device MAC Address hash of the M2M device,
the M2M device considers that the BS triggers uplink data transmission.
The format of the message is shown in Table 166a.
Syntax
M2M_POLL-ADV Message_format () {
Management Message Type = 70

For (i=0;i<Num_M2M_Devices;i++)

The hash is obtained by computing a CRC 24 on the MS 48-bit

[Remedy2 :] Modify texts as following in page 8 line 26 :
[Note – Remedy2]: Action code for uplink report shall be included for a group paging case as well.
11.17.3 M2M group paging parameter
The following M2M group paging parameter TLV may be included in MOB_PAG-ADV message.
The following TLV element shall appear in each M2M group paging parameter TLV

0b1: Send uplink data

[Remedy3] Add new subclause 6.3.23.6, in page 3 line 31 :
6.3.23.6 BS Broadcast Paging message
For a BS Broadcast Paging message to be transmitted to indicate the presence of DL traffic pending, there shall be at least a packet in
the DL traffic whose Paging Preference indicates paging generation.
MOB_PAG-ADV may be used to poll M2M devices for periodic uplink non-realtime data transmission for fixed devices. The interval
of periodic uplink data transmission should be longer than or equal to the paging cycle. When an M2M device receives the DREGCMD message with the Transmission Type set to 1 and Max number of paging cycle TLV, the M2M device shall wait for the
MOB_PAG-ADV as long as Max number of paging cycle * paging cycle before sending uplink transmission.
If the M2M device does not receive at least one MOB_POLL-ADV or MOB_PAG-ADV with Bit 3 set to1 within the Max number of
paging cycle * paging cycle, it may send RNG-REQ message with reception of paging message indicator Bit0 set to 1.
